Abstract

744,356. Digital electric calculating apparatus. STANDARD TELEPHONES & CABLES, Ltd. May 21, 1952 [May 23, 1951], No. 12816/52. Divided out of 744,352. Drawings to Specification. Class 106 (1). Electrical equipment for combining different items of intelligence comprises a plurality of groups of intelligence sources, an equal plurality of synchronous reading devices for reading the plurality of groups of intelligence sources and means for deriving a plurality of outputs each dependent on the combined intelligence from corresponding sources in the plurality of groups of sources. The detailed description is the same as that in Specification 744,352, but the claims differ in scope. Specifications 711,561, 732,341, 744,357 and 744,358 also are referred to.
